Marine Diesel Two Stroke Engine - How it Works!

amazing animations and clean explanation, congrats!!

Great video thank you

If you had ever worked on a ships engine for real, you would know that they are not called "injectors (you get them on truck engines) they are called "fuel valves", and its not "lubrication oil", its "lubricating oil". The chat about "charge air" being called that because it comes fro a turbocharge is not the case: its charge air because it charges the cylinder. So many small errors spoil this for me, but then I was a 3rd engineer before I left the sea, not a second-trip cadet

It is quite good and better understanding of the engine

Thank you so much for this video ❤

Keep it up 💪 amazing video

To reduce internal power absorbtion, is there a process for venting the 20 psi air below the piston on the power stroke ?

Very satisfactory explanation and illustration, really from a well experienced engineer, thanks a lot, greetings from Türkiye.

Thank you very much sir, for sharing very explained videos, I have learned so much informartions your sharings,
I wish contiuned success

No sir! Thank YOU for your time!!! Excellent work!

This video is really good in how he explains this machinery but I wish he could include music and sounds to fill in the silence.

i love how you say "guys and girls"

What a wonderful ship you've drawn. So much to learn from watching your video. Thoroughly enjoyed it....

another great vid, just discovered this channel, feels like i've found a hidden gem!

Can I ask what application is this Sir? This is very useful to teach students of Maritime schools studying Marine Engineering

We keep HFO at 45 deg C to transfer from storage tanks to settling tanks. In settling tanks we maintain a temperature of 85 deg C. After that, before injection in the engine the temperature is increased in fuel module to 125 deg C at a 7 bars. pressure

why does the ladder rung was not horizontally straight?

A truly excellent video...thank you !

Thank you. That's very informative. When the piston is on its compression travel uncovers the air inlet ports will the the air pressure at one and a half atmospheres from the manifold, and the negative pressure created by the rising piston, will the void become pressurised above ambient pressure? Would that pressurised air then be forced back into the charge air manifold by the combustion stroke? Alternatively are there valves to negate that, but just not shown?

And it will cause a faster maintenance on the filter, as that paper adds restrictions

And in the beginning one prop is in forward and the other reverse!

Very cool video. I'll watch the others.

The right propeller is spinning in the wrong direction. ...or it's pitch is incorrect.

Baby TeSla kingDom 😍 love 😍👉💚🙏

everyone besides Americans and i mean every single other country, use metric by the way incase any young viewers are here.

very cool! 😁😁👍👍

AWESOME video !! Thank you !!

I apologize for being a grammar Nazi, but an educational video like this shouldn't be using "times" as a verb. The proper word is multiply.

Everybody talks "driving electric cars" but the vast majority of sips are still driving with Heavy Fuel Oil. We have to overcome this antediluvian concept of "nations", at last. We have to grow up as humans. We all live on an insignificant pebble thats drifting through cold nothingness. What's wrong with all the people who don't get it? How ignorant can you be? Heavy fuel oils - why? Because of greed.

My dawg, all i knew was suck squeeze bang blow. This was game changing. Thank you for making it digestable, fascinating (like the facts and scales brought it home) and enjoyable. hats off lad!

Were I designing that ship, I would put 2 huge variable-pitch propellers on it, 1 on each side.
When you needed to apply the brakes (you would wish your ship had brakes, if you were about to hit something) You reverse the props"") i.e. rotate the blades of the propellers so they stop pulling the boat forward , and start pushing the boat backwards. Eventually this will put your ship into reverse, but before that happens, this will cause it to slow down. Thus the propellers will act like a brake or a reverse gear. You can do this while landing an airplane.
When you reverse the pitch of the starboard prop whilst leaving the port prop alone, they will attempt to make your ship rotate with the rudder being the axis. This will enable you to go around a corner. Think about it.

Thank you! For a well presented, detailed look inside these engines and a closer look at this genius engineering.

Exhaust emissions from marine diesel engines comprise nitrogen, oxygen, carbon dioxide (CO2), carbon monoxide (CO), oxides of sulphur (SOx), nitrogen oxides (NOx), hydrocarbons, water vapour and smoke. Oxides of nitrogen and sulphur are of special concern as threats to vegetation, the environment and human health.

2am algorithm gods and goddesses have blessed me this night with a new channel to binge.

Amazing knowledge experience ❤❤❤
Thanks to increasing in knowledge

Your video is fascinating. Thank you so much for your efforts. Best Wishes

why is turning gear placed on port side of engine on every ship?

The air filter is to stop humans and clipboards getting swallowed i see.

Dude this was awesome man

PNP cb pora pak?

very well explained

My Dad served on an armored cruiser (USS Rochester, coal fired sister ship of the Maine) at the end of WWI. Engine rooms then were an even more unpleasant space than they are now, but at least the black gang could cook stew on their shovels in the furnace (not good for efficiency, though). Great tutorial, thank you.

That turbo will fit on a 5.9 Cummins

Will it fit in a Miata? Very important I need to know
